Alignment of two putative LWS opsin regulatory elements (CNE 7a and b) in fishes. A) Alignment of CNE 7a from five fish genomes to dre-miR-726. This region is highly similar among all fish species examined. Black box indicates the mature microRNA sequence. B) Alignment of CNE 7b from five fish genomes to the human LWS-LCR. These sequences show regions of high similarity between humans and fishes. Asterisks (*) indicate positions that are identical among all taxa; colons (:) indicate positions that are identical among four out of five taxa. Boxes highlight conserved transcription factor binding sites.
